Im new to Sencha Touch.
First of all ive to say that this is amazing work. thank you!

im a little lost in Ext.extend.

i just want to build a class that contains of a simple text-label, a toggle and a slider.
i want to add event listeners to the controls.
but i cant figure out how to access them to add listeners and so on.
pls see comments in the code below....

//id like to access the item from here, but this.down does not work...
//how can i access the child-items from the construcotr?
//TypeError: Cannot call method 'slice' of undefined
//console.log(this.down("#myItem"));

//id like to access the field in the main-class, but here the context is DOMWindow, so its not possible ...?
//TypeError: Object [object DOMWindow] has no method 'up'
//'foo4' :this.up("#myclass_id").foo2
